So, a long time ago, people figured out how to make something called iron. They would take rocks that had iron in them and heat them up really, really hot. This made the iron inside the rocks melt into liquid and they would drain it out into a mold to make it into a shape they wanted, like a tool or a weapon.
But making iron was really hard work! First, they had to find rocks with iron in them, which wasn't always easy. Then, they had to break the rocks into really small pieces using a hammer or something like that. After that, they had to put the small pieces of rock into a furnace, which is like a big oven but much hotter.
The furnace had to be really hot for a long time, and people had to keep adding more pieces of rock and keeping the fire going. This was called smelting. The liquid iron that came out was really hot, so people had to be careful not to burn themselves. They would pour the liquid iron into molds, which were usually made of sand or clay.
Once the iron cooled, they could hammer it into the shape they wanted. They would use special tools to do this, and it took a lot of strength and skill. Sometimes, they would also use heat to make the iron easier to work with.
It was a really tough job to make iron, but it was really important because iron was used for lots of things, like weapons, tools, and even building structures. People had to work really hard to make sure they could get the iron they needed to survive and thrive.
